Ask for OpenAI key in interactive mode

[rabisg]

Is your feature request related to a problem? Please describe.
Right now at the end of the installation step, the cli prints this:

Done!
Get started:

cd foo

touch .env

Add your API key to .env:
OPENAI_API_KEY=sk-your-key-here

pnpm run dev

It would be better to ask for the key in interactive mode, create the .env file ourself and start the server directly

Describe the solution you'd like
In interactive mode it would be better to get the server up and running and give users an url to start working with

Additional context

• In non interactive mode skip this step entirely.
• No need for --openai-key=<> flag for now

Unless urgent or prioritised by the team, I think it can be part of a bigger change to the CLI, where the CLI can take args such as - which design system to use (OpenUI DS, HeroUI, Material, etc), which template to bootstrap (chat, dashboard, etc). Also lays foundation for prompting for which AI SDK to use while bootsrapping (OpenAI, Vercel, Gemini, etc) Wdyt?

@AbhinRustagi this aligns very well with what we had in mind. The first thing we wanted to do was take an arg that maps to the examples. something like the template you just mentioned. next would be design system and framework but that would require some serious restructuring of the examples and the design system stuff. We would definitely want to see this happen!
